HEATING STOVE AND RADIATOR THEREFOR.

Application filed May 14,

T 0 all whom it may concern:

it known that I, ARTHUR L. ZWIsLER, a citizen of the United States,residing at the city and county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Heating Stoves andRadiators Therefor, of which the following is a specification.

This invention relates to improvements in heating stoves and radiatorstherefor.

My improvements are especially designed for embodiment for use in oilstoves such as are commonly and well-known to the trade as blue flameoil stoves which stoves are commonly provided with a chimney and I haveillustrated my improvements as embodied or adapted for use in suchrelation. My improvements are, however, adapted for use in connectionwith gas plates and other gas burners where it is desired to use thesame for heating purposes.

The main object of this invention is to provide an improved heatingradiator which is very eflicient in the matter of heating capacity,circulating the air and supplying humidity to the heated air.

A further object is to provide an improved heating stove or attachmentfor oil burning stoves in which the products of combustion aresubstantially odorless.

()bjects pertaining to details and economies of my invention willdefinitely appear from the detailed description to follow.

1 accomplish the objects of my invention by'the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisapplication, in which:

Fig. I is a side elevation of an oil burning heating stove embodying thefeatures of my invention.

Fig. 11 is a vertical central section through my improved radiator on aline corresponding to line 2-2 of Fig. I.

F ig. III is a plan view of the oil burner stand of the structureillustrated.

Referring to the drawing I provide in the embodiment of my improvementillustrated an oil burner designated generally by the numeral 1 providedwith a chimney 2, the whole being mounted and supported in a stand 3having a top 4 with a central open- 1923. Serial No. 638,849.

ing and an annular series of openings for the passage of heat and theproducts of combustion. My improved radiator is designed tobe placed onthis stand or when 1t is removed a cooking utensil may be placedfthereon.

My improved radiator comprises a cylindrical base 5 having a downwardlyflaring flange 6 adapted to rest upon the top 4: of the stand asindicated. Within this base is an annular water reservoir 7 open at thetop, the reservoir being supported on the inwardly projecting flange 8formed on the upper edge of the lower section or flaring portion of thebase. This water receptacle is arranged in a spaced relation to theWalls of the base providing an annular chamber 9 having an annularseries of discharge openings 10 adjacent the top thereof. ihe annularreservoir provides a central flue or passage 11.

I provide a drum or casing 12 having a downwardly flaring flange 13 atits lower end embracing the upper end of the base member. The top 14: ofthis casing is provided with a damper 15 so that the heated air andproducts of combustion. may be allowed to escape at the top of thecasing if desired. Centrally within the casing is a fine 16 telescopingwith the upper end of the flue or passage 11 so that the heated air andproducts of combustion pass upwardly from the burner and are dischargedat the top of the casing, a baflle 17 being supported in spaced relationto the upper end of the flue preventing the discharged heated air andproducts of combustion from impinging directly on the top. When thedamper is closed the heated air and products of combustion are compelledto pass downwardly through the drum 12 and are discharged through theopenings 10.

I preferably arrange a flange-like baffle member 18 at the lower end ofthe drum or casing 12 providing a restricted passage 19 around the flue.This. brings the current of air in close contact with the side of theflue so that it effectively absorbs the heat therefrom. The water in thereservoir becomes heated so that moisture is added or supplied to the.air in the form of vapor and it is found that the structure ispractically odorless.

I have illustrated and described my improvements in a very practicalembodiment. I have not attempted to illustrate lUU flange at the bottomthereof adapted to rest on the top of the stand, an annular waterreservoir disposed within said base member in spaced relation to theside walls and bottom thereof and providing a surrounding annularchamber and a central passage, said base member having an annular seriesof discharge openings adjacent its upper edge opening to said annularchamber, a casing having an outwardly flaring flange at the bottomthereof embracing the top of said base member the to of said casin bein7 P va a provided with a damper, a flue disposed centrally wlthin saidcasing and adapted to telescope w1th said passage in said base memberwhen the casing is in position, and a baffle plate disposed above and inspaced relation to the top of said flue whereby when said damper isclosed the heated air and products of combustion pass upwardly throughthe central flue and downwardly at the outside thereof to be dischargedthrough said discharge openings in said base member, said casing havingan inwardly projecting annular flange at its lower end disposed inspaced relation to the top of said water receptacle providing arestricted passage from the casing,

2. In a heating stove, the combination of a burner provided with achimney, a stand for said burner provided with a top adapted to receivea radiator, a radiator removably mounted on said top and comprising abase member having an outwardly flaring flange at the bottom thereofadapted to rest on the top of the stand, an annular water reservoirdisposed within said base member in spaced relation to the side wallsand bottom thereof and providing a surrounding annular chamber and acentral passage, said base member having an annular series of dischargeopenings adjacent its upper edge opening to saidannular chamber, acasing having an outwardly flaring flange at the bottom thereotembracingthe top of said base member, the top of said casing being provided witha damper, and a flue disposed centrally within said casing and adaptedto telescope with said passage in said base member when the casing is inposition, whereby when said damper is closed the heated air and productsof combustion pass upwardly through the central flue and downwardly atthe outside thereof to be discharged through said discharge openings insaid base member.

3. In a heating stove, the combination with a burner, of a radiatorcomprising a base member, an annular water reservoir disposed withinsaid base member, said base member having discharge openings at its upper end, a casing mounted on said base member to close the top thereof,a flue disposed centrally within said casing and adapted to coactwit-h'said passage in said base member when the casing is in position,and a baifle plate disposed above and-in spaced relation to the top ofsaid flue, whereby the heated air and products of combustion passupwardly through the central'flue and downwardly at the outside thereofto be discharged through-said discharge openings in said base member,said casing having an inwardly projecting'annular flange, at its lowerend disposed in spaced relation to the top of said waterreceptacleproviding a restricted passage fromthe casing.
